I have bought gear from these guys before and they very kindly pass the shipping fees on at cost. But unfortunately due to contracts with the following brands, they are unable to ship any of their products outside the US.

Lots of US retailers will happily ship you gear in Australia that their website says can't be shipped internationally. Lots of experience here.

If you're looking for WM, you might like to try Hermit's Hut. They regularly have a free international shipping deal on WM. That will save you in the order of US$40-$50 straight away. Considering that WM aren't often on sale, it's not a bad deal.

I picked a brand new WM Highlite up 2 years ago on the US eBay site US$248 (approx AU$280) won the bidding and postage was reasonable (approx $20). I also bought a top of the range REI bag for my partner on US eBay as well - far cheaper than Australian retailers. I really don't bother with the local retailers any more apart from maps and minor items.

It is also worth checking out UK retailers for gear. A short Neoair cost me AU$150 all up from Webtogs rather than $250+ in Australia. UK retailers don't appear to have the same "do not ship to" rules as the US retailers and often the postage is cheaper.
